What is the best way to compare strings in Java?

The right way of comparing String in Java is to either use equals(), equalsIgnoreCase(), or compareTo() method. You should use equals() method to check if two String contains exactly same characters in same order. It returns true if two String are equal or false if unequal.

What is == and equals in Java?

Can you use == with strings?

== compares the exact values. So it compares if the primitive values are the same, or if the references (addresses) are the same. That's why == often doesn't work on Strings, Strings are objects, and doing == on two string variables just compares if the address is same in memory, as others have pointed out. .

How do you make two strings equal in Java?
